Exploring Forces Class 8 Short Question Answer

Question 1.

What is a force?

Answer:

A force is a push or pull on an object that results from the interaction between two or more objects.

Question 2.

How does friction affect the motion of a ball rolling on a flat surface?

Answer:

Friction opposes the motion of the ball, causing it to slow down rather than increase its speed.

Question 3.

What happens when two balloons rubbed with a woollen cloth are brought near each other?

Answer:

The balloons will either attract or repel each other depending on the charges they acquire from the rubbing process.

Question 4.

What is the role of friction in everyday activities, and how can it be both beneficial and detrimental?

Answer:

Friction is essential for walking, driving, and holding objects. However, excessive friction can cause wear and tear on surfaces and increase energy consumption in machines.

Question 5.

How do different surfaces affect the amount of friction experienced by objects in motion?

Answer:

Different surfaces have varying textures and materials, which influence the amount of friction. For example, rubber on concrete provides more friction than ice on metal, affecting how easily objects can slide or roll.

Question 6.

How does the mass of an object affect the gravitational force acting on it?

Answer:

The gravitational force acting on an object is directly proportional to its mass. This means that heavier objects experience a greater gravitational pull than lighter ones, which is why they fall faster when dropped from the same height.
